Testing my first Pultec type EQ

mayo · 20 Jul 2011

Hello,

I think that the noise level of -140db is very high for Pultec-type EQ. But maybe you are developing a modern version, then it's ok 😉

- Parallel configuration for low - Fo different in gain and attenuation - Bell for the high frequencies, - Interrelationship between Q - gain, For. - Gain, Q - For. what you might call "features music"

Oversampled (2x) and simulation for harmonic distortion, generating even and odd harmonics, and noise level of -140 db.

You help me with the first test?

Already thank you very much for your input.

Sorry for my English.

It sounds fine to me. If you are happy on how it sounds it really doesn't matter what anyone else thinks.

Cheers!

Sounds pretty smooth to my ears - though, of course, I don't have the money for a genuine Pultec to compare with! 😉 CPU load is also good for an oversampled design - even my Atom notebook will run several instances without problems. One very little thing I noticed - the input and low-boost knobs seem to have different mouse sensitivity to the other knobs - but not enough to be a problem.

I am pretty sure that a 1960's engineer running an analogue Pultec through a tube console from analogue tape would have been very very pleased indeed to get -140dB noise!! 😉

trogluddite Many thanks for your help, I will solve the problem sencibilidad.

How do you test the cpu consumption?, Is there any software to measure it or just check it with the consumption of CPU in your DAW?

Greetings and thank you very much for the help.

I usually try to test by using the plugin in a DAW, as that is how the customer will use them. That way, you can also test with lots of instances of the plugin to get a bigger and steadier reading - using just one plugin, the number is often too small to be meaningful. Comparing with other similar plugins is the best thing - the % is useful for the developer (to see if edits make it smaller), but not so useful for the customer because they will have a different PC.

Also, the CPU measure on the SM window is not very reliable.... - SM only uses only one CPU core, so for DualCore, QuadCore, 'i' CPU etc. the reading is distorted. - only measures audio CPU, but not CPU used by 'Green' parts/knobs/graphics etc. - some of the % comes from the ASIO/DS components, not the plugin. ....sometimes just closing and re-opening SM will change the reading, or even just selecting/editing SM components on the screen. Using Windows Task Manager CPU meter will give a more useful reading.

My favourite is to use Reaper - that DAW can show individual CPU load for each track, so it is very good for quick tests. It is also very powerful and very cheap - just for testing you could use the free download (all functions will work, it just has a 'Buy This' screen at startup).

I bought 6 months ago, excellent software at a great price

thank you very much for your help

Sure I meant very low, not high 😇
